Brick Estimator
Estimate a first-pass brick quantity from net wall area, face dimensions, mortar-joint thickness and a waste allowance.
How to use this calculator
- Enter the net wall area after subtracting openings, brick face dimensions, joint thickness and an appropriate waste allowance.
- Check the labels and units before using a result outside this page.
- Change one input at a time if you want to compare scenarios.
Formula and method
Module area = (brick length + joint)(brick height + joint); count ≈ net wall area ÷ module area
- Module area = (brick length + joint)(brick height + joint); count ≈ net wall area ÷ module area
- Bond pattern, openings, cut bricks, actual sizes and supplier packaging can change the order; use manufacturer or mason guidance for a final take-off.
Worked examples
Worked example
Net wall area 10 m², brick 215 × 65 mm, 10 mm joints and 10% allowance.
The modular estimate is adjusted upward by the allowance and rounded to whole bricks.
